Manage Map Rule Resources

The resources available on a GigaVUE H Series line card or node changes depending on the combination of criteria in place on the line card or node as a whole. In general, adding or removing MAC address, UDA pattern match, or IPv6 criteria in the map rules bound to a line card or node changes the type of filter template used on the line card or node. This can result in a brief interruption of traffic as the new template is applied.

Template Groups

The template groups are listed sequentially from least resource-intensive to most resource-intensive:

•

IPv4 Only – This is the default filter template, including all IPv4 arguments without any MAC addresses, UDA data patterns, or IPv6 arguments. This template can support the IPv4 and related filter criteria, including VLAN tags, source/destination ports, protocol criteria, and so on.

•

IPv4 and MAC Addresses – This template combines MAC address criteria with the standard IPv4-related criteria. When MAC address criteria are in use, map rule resources are decreased.

•

IPv4 and Single UDA Data Pattern – This template combines one of the two available UDA data patterns with the standard IPv4-related criteria. Using a single UDA criteria does not affect the total number of drop map rules available, but it does decrease the number of pass map rules available.

•

Both UDA Data Patterns – This template uses both UDA data patterns but removes the ipv4 argument. Drop map rule availability is not affected by adding a second UDA data pattern, but pass map rules are decreased again from what was available when only a single UDA was used.

•

IPv6 Arguments – This template adds the use of the IPv6 argument. IPv6 criteria are resource-intensive, significantly decreasing both drop and pass map rule capacity, as shown in the following table. Note also the changes in available criteria and available resources.

The map rule criteria available in each filter template (or “group”) is shown in the following table.

Note:  In addition, you can use flexible filter templates on GigaVUE-HC3 to support up to 6K rules per slot. On GigaVUE-TA100 and GigaVUE-TA200 they support up to 6K rules per pseudo-slot, or 24K rules per node.. Refer to Flexible Filter Templates for details.
